[LayoutNG] Rebaseline text failures in compositing/

compositing/massive-scale-interest-rect.html
  No longer different from the base, removed flag-specific.
compositing/geometry/transfrom-origin-on-zero-size-layer.html
  Matches better to the base, but text width differ by 1px.

Probably from the recent fix for outline thanks to atotic.
